Quoted from RoyalJack:
Going to check now lol
EDIT: I forgot, I did find that bag, it had some keychains in it.
Damn...sorry. I figured it was a long shot these days. It's definitely worth at least checking with your distributor and Stern though. At least as of a few years ago they would send "freebie" bags of stuff to tournament directors to give out at events, and there were almost always random plastics, target decals, stuff like that mixed in. So hopefully they do have spares available. I wouldn't hold my breath, but it's worth asking before dropping the money on a full set.
